F-drones said it plans to develop drones that can deliver 100 kilos over distances of 100 kilometres to ships and offshore platforms by the second half of 2021.

Deliveries offshore are currently being done by small boats and helicopters, but the company said the use of its unmanned vehicles will save up to 80 percent of the cost and is more environmentally friendly.

Singapore's civil aviation authority has got behind the use of drones and is working with industry players as it seeks to shape regulation for the sector.
